Patent GB-755688-A (GB)
Abstract: 755,688. Vibration detectors. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. June 10, 1954 [June 12, 1953], No. 17088/54. Class 40 (4). [Also in Group XXXVIII] A device for measuring mechanical vibrations comprises a moving system including a coil suspended by one or more springs so that the coil may vibrate axially in a magnetic field, and two or more additional springs each compressed between a fixed point and a point on the moving system so as to exert a force perpendicular to the coil axis when in the equilibrium position but arranged to lower the natural frequency of the moving system. The weight of coil carrier 1, 2, 2a, 2b, is balanced in all positions thereof by the tension of spring 13 while weak blade suspension springs 3, 4 control the motion of the coil 5 through the air gap of the magnet 6, 7. The forces exerted by additional springs 20 which bear on adjustable screws 19 and on the carrier at 22 balance when the carrier is in the equilibrium position. When it is displaced axially the components of the spring forces along the axis oppose the restoring force of springs 3, 4, thereby reducing the natural vibration frequency of the system. To prevent jolts giving rise to lateral movement of the carrier from damaging springs 3, 4 the carrier is provided with a pin 15 engaging (with sufficient clearance to prevent resistance to axial motion) a hole 16 in a fixed member, and at 2b with holes engaged by similar pins 17, 18 fixed to the magnet structure thereby preventing excessive lateral motion. The compression springs need not all be in the same plane, in which case torque reaction is provided by springs 3, 4.

Patent GB-2011222-A (GB)
Title: Signal transfer system for time division switching centres
IPC: H04Q11/04
Filed: 1978-11-21
Abstract: This relates to line signalling arrangements for use in a time division multiplex (TDM) switching centre in which pulse code modulations (PCM) is used. In a "supervision" phase, line signalling is extracted by an access control unit (ACU) at the centre's input for transmission to the centre's central processors however in a "register" phase line signalling is exchanged on a single bit of the PCM channel through the connecting network between the ACU and a multiregister (MR) used for call control. This handles the whole of the signalling functions for that channel in conjuction with the central unit. The control of the ACU and the MR as far as the temporary implementation of this signal transfer system and its control are concerned is effected by setting up a mutual recognition procedure between ACU and MR by detecting a particular signalling condition.

Title: Making mineral insulated electric cable
IPC: H01B13/004
Filed: 1980-02-01
Abstract: In the manufacture of mineral insulated cable, by a continuous process in which the tubular sheath 1 is formed by bending and seam welding travelling metal strip, and insulating powder and conductor wires are continuously delivered into the sheath, one wire 10 is fed through a guide tube 8 extending into the sheath 1 beyond the weld point 5, and having an aperture 12 in its wall adjacent to the weld area. The wire so exposed directly to the heat from the weld conducts excess heat away from the weld, thus preventing thermal damage, in particular to a powder delivery tube 7 if `present. The guide tube is so arranged that powder is excluded from the weld area. When the sheath is formed of an oxidisable metal such as copper, a continuous stream of rare gas is delivered to the underside of the weld area. Forms of apparatus for carrying out vertical and horizontal processes are described. The cable may be wiring cable for general purposes, heating cable, thermocouple cable and heating elements for electric cookers. <IMAGE>

Patent GB-2091891-A (GB)
Title: Apparatus for measuring the resistance of a length of elongate electrical conductor
IPC: G01R27/14
Filed: 1981-11-24
Abstract: Apparatus for measuring the resistance of a wire comprises steel pulleys (1 and 2) on a steel shaft (3) which also carries multi-turn torodial windings (4 and 5). The winding 4 acts as a supply winding energised from oscillator (6) via voltage controlled attenuator (7) and power amplifier (8). Due to current induced in the shaft, current flows in the length of wire between the pulleys. This current is sensed by the other winding (5), whose output voltage is amplified (9) and rectified in a rectifier (10), whose output controls the attenuator. A difference in the resistance of the wire between the pulleys from the value of a known resistance causes a different current to flow than when the known resistance is connected. This change in current produces a change in the output voltage of winding (5) whereby the attenuator (7) is adjusted until the voltage fed to winding 4 is such that the same current flows as when the known resistance is connected. The change in voltage is directly proportional to the difference in the resistances; thus, after rectification (11) the voltage fed to the winding 4 is passed to a digital voltmeter (12) calibrated directly in Ohms. <IMAGE>
Patent GB-2090681-A (GB)
Title: Data processing machine with split-cycle cache memory management
IPC: G06F12/08
Filed: 1982-01-05
Abstract: A data processing machine in which the cache operating cycle is divided into two subcycles dedicated to mutually exclusive operations. The first subcycle is dedicated to receiving a central processor memory read request, with its address. The second subcycle is dedicated to every other kind of cache operation, in particular either (a) receiving an address from a peripheral processor for checking the cache contents after a peripheral processor write to main memory, or (b) writing anything to the cache 24, including an invalid bit after a cache check match condition, or data after either a cache miss or a central processor write to main memory. The central processor can continue uninterruptedly to read the cache on successive central processor microinstruction cycles, regardless of the fact that the cache contents are being "simultaneously" checked, invalidated or updated after central processor writes. After a cache miss, although the central processor must be stopped to permit updating, it can resume operations a cycle earlier than is possible without the divided cache cycle. <IMAGE>
